sheet -flow stormwater runoff to adjacent streets. A new localized low point will be created on the westerly park property boundary that will result in some standing water during and following larger rain events for a period of time, which currently occurs just closer to Center Street. A quote for completing this work through The COR Infiltration Basin Improvements project was requested this spring from the project contractor, Northern Lines Contracting. They responded that they are not interested in completing the work at this time. Staff then obtained verbal quotes for this work from other contractors. The quotes generally ranged between $55,000 and $63,000. Following Council approval, Staff will solicit at least three written Requests for Quotes for completing this work in accordance with the City's Purchasing Policy. Notification: Notifications are not required for this case. Following Council approval to solicit Requests for Quotes, Staff will request quotes directly from at least three contractors. Observations/Alternatives: Observations: The 8,000 cubic yard sand stockpile is currently situated on the City -owned property north of the new infiltration basins, which is currently marketed for sale. Relocating the sand to the Municipal Plaza park site will allow for more timely development of the Municipal Plaza park, remove the stockpile from the City -owned property marketed for sale, and reduce the amount of fill ultimately needed to develop The COR. It is currently estimated that The COR will require over 300,000 cubic yards of clean fill to fully develop. Alternatives: Alternative #1: Motion to recommend City Council authorization to request written quotes to relocate the sand stockpile north of the COR infiltration basins to use as fill on the Municipal Plaza park property. Funding Source: The estimated cost to relocate the sand stockpile to Municipal Plaza park is $60,000. As previously discussed, this work was originally proposed to be completed through the COR Infiltration Basin Improvements project, which is being funded by Stormwater funds. Since this work must now be completed outside of that contract, Staff proposes to use a combination of Stormwater funds and Park Dedication funds. Stormwater funds are proposed to pay for all work required to load and haul the sand to the Municipal Plaza park property, and to establish new turf on the current stockpile site. Park Dedication funds are proposed to pay for all work required to fill the Municipal Plaza park property including stripping, stockpiling and re -spreading topsoil, leveling and compacting the sand in 1-foot lifts, and establishing turf. The Request for Quotes will include pay items for each task specific to each site so final costs can be allocated appropriately between the funds. Recommendation: Staff recommends Alternative #1 for reasons noted herein. On June 16, 2020, the Public Works Committee unanimously adopted a motion to recommend City Council approval to solicit quotes to relocate the sand stockpile from the COR Infiltration Basin site to Municipal Plaza park. A draft copy of the meetings are attached for reference. Though the Public Works Committee meeting minutes provide direction to complete the work after Happy Days events are over, based on recent discussions with Council Staff is of the understanding that the Municipal Plaza park property will not be used for Happy Days activities so Requests for Quotes will not require work to start after
